13 Claims.

When in the weaving operation the warps in a loom are exhausted or run out it is usually desirable to continue the warps, and thus the weaving operation, by uniting the ends of the running warps in the loom to the ends of a fresh set of warps, and the object of this invention is to provide a novel method and apparatus for thus uniting or continuing the warps.

The object of the invention is further to provide such a method and apparatus inwhich the ends ofthe warpsare united by means of an adhesive, thus eliminating knots or other obstructions hindering the passage of the united warps through the various mechanisms of the loom.

The object of the invention is further to enable the uniting of the warp ends to be performed rapidly and efliciently and without the use of complicated or expensive apparatus.

The nature and objects of the invention willappear more 'fully in the accompanying drawings and will be particularly pointed out in the claims.

The drawings illustrate a simple'and preferred form of apparatus embodying the invention and suitable for carrying out the method of the invention. Since the invention is applicable to looms of a wide variety of types, and sincethe mechanism of looms is familiar to those skilled in the art, it is only necessary to illustrate diagrammatically the elements of one type of loom in order to disclose the invention. For that purpose a loom of that type employing two warp beams,- one above the other, has been selected as showing the applicability of the invention to the continuing of the warps for each beam.

It will be understood also that the mechanism illustrated for carrying out the invention in connection with the loom is also in somewhat diagrammatic form and that the proportion and arrangement of the various elements may be varied as required.

In the drawings:

Fig. 1 is a side elevation, partially broken away, showing the main elements of the loom together with a preferred form of the apparatus for uniting the warps associated .therewith;

Fig. 2 is a view, partially broken away and in perspective, illustrating the principal elements of the apparatus shown in Fig. 1, and illustrating the method employed in securing the overlapping of the warp ends;

Figs. 3 and 4 are side elevations of the elements shown in Fig- 2 illustrating steps in the carrying out of the methodax V.

Fig. 5 is a top plan view of the main elements of a slasher illustrating the means employed for segregating the ends of the warp of a supply beam;

Fig. 6 is a detail of a portion of one element of the divider employed in the apparatus.

The loom illustrated comprises a suitable frame I, only a portion of which is shown, carrying at the bottom a running warp beam 2, and at the top a second running warp beam 3. The running warps lead from these beamsthrough usual heddles 4 and beat-up reed 5 to. the fell 6 of the cloth being woven. The warps I from the lower running beam are'shown as running over a pair of rolls 8 on their way to the heddles and in the same way the warps from the upper running beam 3 are shown as running over a pair of rolls 9 and then over rolls l0 and H on their way to the heddles.

One feature of the invention involves the maintaining segregated with a separator of the running warps as they enter the loom from the running beam. This term separator is here used to indicate means which acts to maintain segregated the warps in a sheet of warpsand may include more than one element. Such a separator may consist simply of a reed, similar in general to that employed on the lay, when it is practical to maintain the warps with one in 3 each dent. Where it is desired to run two warps in each' dent of a reed then such a separator may include lease rods which, together with the reed, enable the segregation of theindividual warps to be maintained. In the case of the upper beam illustrated the separator is shown as comprising simply a reed l2 removably mounted on the loom frame between the rolls 9, while in the case of the lower beam 2 the separator includes a reed I3 removably mounted on the loom between the rolls 8 and a pair of lease rods M of the usual type.

The invention also requires that the ends of the warps on the supply beam also be maintained segregated and for that purpose another separator is employed which in turn may comprise simply a reed or a reed together with a pair of lease rods. The application of the separator to the ends of the warps on the supply beam may be effected in any suitable Way, but conveniently may be done at the time the warps are passing through the slasher and wound upon the supply beam. Such an arrangement is illustrated in Fig. 5 where the fresh warps l5 are shown passing through the slasher I6 and being wound upon a supply beam I1. In such a slasher the warp ends are usually segregated by an adjustable comb, such as 18. In this case a reed i8 is removably mounted in the slasher and also when required a pair of lease rods 20 are mounted in the slasher, thus to enable the warps to be held segregated by the separator element at the conclusion of the slashing operation.

With the running warps in the loom thus maintained segregated, and with the ends of the warps on the supply beam thus maintained segregated, the apparatus further illustrated at the right-Of Fig. 1 and in Figs. 2, 3, and 4, is provided for securing the ends of the warps on the supply beam to the ends of the running warps in the loom so that the weaving may proceed with the warps continued.

The apparatus thus illustrated in a simple and preferred form comprises a suitable frame shown as having a base 2| mounted on rollers 22 'and upright side members 23 and horizontal side members 24 and on this frame are provided supports 25 for the gudgeons 23 of the supply beam l1, while on the horizontal members 24 are removably mounted the main elements which extend transversely of the frame between the side members.

In carrying out the method of uniting the warp ends the supply beam is'mounted in the gudgeon supports 25 on the supporting frame and the frame is preferably moved -up to the rear of the loom so as'to be closely adjacent thereto as indicated in Fig. 1.

r The supporting frame at the rear end, or that toward the loom, is provided with a roller 2-? extending transversely and resting in supports 28, Next, supports 29 are provided at each side for a separator reed, such as 1-2, of the running warp ends. Next is provided a divider-carried on a support 30 extending transversely of the frame and removably mounted thereon. Next is provided another pair-of supports 3l for areed, suchas ['9 forming the separator for the supply warp ends. Next -a roller 32 extending transverselyef the frame and mounted in-supports 33.

The ends of the running warpsand the ends of the warps -of the supply beam areseverall-y overlapped, in carrying but the invention, in a series of parallel-individual channels, and for that purpose the divider is providedand-is illustrated in a preferred form. As shown it comprises a baseof two separated parts 34 mounted on the formed therein. A series of-thin plates 38 are re-' movably fittedintothese slots so that between the plates are formed similar parallel transverse gated ends of the running warps is placed position on the supporting frame. -In the illustration it is assumedthat the warps of the upper running beam are to be united to those :of the supply beam and in this .case therunning warps are severed at 39 and the reed :12 mounted in the supports 29 with therunning-warpslying:over

the roller orguide barl] and projecting through,

with two overlapping in each channel.

the reed. The warp ends 15 extending from the supply beam now mounted on the frame are carried up over the roller or guide bar 32 and the reed IQ of the separator segregating these ends is placed in position on the supports 3| with the ends projecting therethrough. When lease rods are employed they are 'at the same time in eachcase positioned between the respective guide bars and reeds.

Next, the ends of the warps on the supply beam and the oppositely facing ends of the running warps are combed into the series of parallel individual channels of the divider so as to cause the ends of theone-set to be overlapped individually in regular sequence upon the oppositely facing individual ends of the other set in the said channels. For enabling this operation to be performed efficiently there is provided a hand comb, such as shown in Figs. 2, 3, and 4, comprising a head 40 with idepending teeth 4| constructed so that the dents :of this comb correspond to the dentsof the reeds .of the separators. This comb is of comparatively short length so that the warpends are combed in sections.

The operation of laying the warp ends incoverlapping relationin the divider may be performed in any desired sequence. Preferably, however, the warp-ends of the supply beam are first .laid by the comb in the divider-and then-the ends of the running warps are laid in the divider overlapping the ends from the supply beam. As 11- lustrated in Fig. 2 in carrying out this combing action the comb is inserted by the operator over the segregated ends-of the supply beam adjacent the reed I9 and then carried over the divider into the'position shown at the left to lay the ends in the individual channels. Then with the comb removed the section of ends 'thus laid is preferably secured and for that -purpose a series of clips '42 are provided ronlthe support 30, one for each section of ends. :In the next *stepthe comb is placed over a section 'of the ends of the running warps adjacent the reed l2 and the comb 'ismoved to'the position indicated at the right in Fig. .3 to -lay this section of ends in the divider channels overlapping the section Ifirst laid. Then the comb is removed and this section of ends referably carried .overand held by one of the series of clips 4.3 provided on a bar 44 removably mounted .onthe supports 33of the frame.

In carrying-out this endsof the warps of the supply beam arepref erably first .laid section by section until all end are positioned in thechannels and .t n theends, n

section in the .channels'until all the en s .;a 'ref laid. .As a result, regardless of the sequence o f. the steps'employed, .all of the .endsare positioned,

Then the overlapping endsare Ladhesivelyse cured together by applying an adhesive :the channels. Forzthis purpose a zrubberlatexghas beenfound iefliciently andxfirmlycto secure the overlapping-ends together. The latex may be dried I by projecting warm air-Ion the; channels and desirably :talcum powder may be sprinkled on .the latex. 1

The 'freeportions .of the 'overlapping ;ends are then :prefera'bly severed closeto the;diyi der :and thus the warps are leftrcontinuous from the sup-.- ply .beam to the :loom. The separator :l9 is then removed from ;the.awarps preferably by removing. the upper head of the. reed,:the. guide :barsj] and I combing operation the 32 are removed fromthe supporting frame, and the divider with its support is separated from thawarps by removingit from the frame and I then, the exhausted running beam having been removed from its gudgeons, the supply beam is placed in position in the loom and the separator, such as I2, restored to its position in the loom.

When lease rods are employed, and consequently there are two dents in a reed, it will be obvious that the sheet of warps may be divided into two parts and each one of these parts successively handled in sections by the combing operation.

The clips provided for holding the compacted ends of the several sections of warps have an important function in that they maintain the warps taut or under slight tension so that when the uniting of the warp ends has been effected the continued warps will run evenly from the supply beam tothe loom.

The invention thus provides a very simple and eflicient method for securing the continuous operation of the loom by uniting the warps from a supply beam to the running warps in the 100111 and also a simple and efiicient apparatus for carrying out the method.'
